The trebuchet was the ultimate military weapon of its day, a highly evolved catapult that could hurl stones weighing up to 300 pounds. The trebuchet uses a failing counterweight to provide the energy needed to hurl the projectile. Kids will have a great time building and operating their own trebuchet while they experiment with momentum and energy transfer.

This trebuchet kit contains pieces accurately machined from carefully chosen lumber and precisely drilled to allow easy assembly. You also get a realistically detailed counterweight box and wooden projectiles that can be hurled up to 15 feet. Detailed, clearly illustrated assembly instructions guide the builder through each step of constructing their trebuchet kit.
